Cui Ning spent about three days in the "Qiankun Cave Mansion", and finally restored his state to the peak.

He took out four porcelain vases and a brocade box made of gold and stone from his body and placed them on the ground.

In each of the porcelain vases is a Tsukidan, and in the brocade box is the Tianluo fruit harvested during the trip to Red Rock Island.

Considering that his own cultivation of the Sun Technique might require a large amount of Heaven and Earth Spiritual Qi if he broke through, Cui Ning put all the spirit stones on his body into the groove on the platform.

It was only when the sea of knowledge suggested that he could cultivate for six months before he stopped.

Things were ready, and next, Cui Ning began to attack towards the foundation building period.

He first picked a pill of Tsukidan and took it, and then began to meditate and cultivate.

The legendary Zhuji Dan is different from those pills that strengthen the foundation and cultivate the yuan.

As soon as Tsukidan took his stomach, Cui Ning felt a cold clear current spread out in his dantian, and then another hot current appeared and hit his body, and then the two energies of cold and hot continued to intertwine in his body.

Cui Ning's face changed drastically, and he realized that this was the Zhuji Dan at work, so he didn't dare to slack off and began to refine the medicinal power.

A day later, Cui Ning opened his eyes, and the feeling of "ice and fire" in his body had disappeared, and now he was left with a completely comfortable feeling, which almost made him moan.

Feeling that the medicinal power of the Zhuji Pill in his body had been completely refined, he found that his cultivation, which he had not improved for a long time, had strengthened a little more.

At this time, Cui Ning sniffled, and his brows furrowed, only to see that his whole body was covered with a layer of black-gray substance, as slimy as mud, and it also exuded a foul smell.

Cui Ning covered his nose in disgust, took off his clothes, rinsed himself with the water technique, and changed into a new one, and then sat cross-legged again.

The first breakthrough was as expected, and it did not succeed in advancing to the foundation building period.

Although he didn't succeed, Cui Ning was not depressed, which was expected, he was already aware of the fact that his qualifications were poor.

If it weren't for the Sun Jue, he wouldn't have had the opportunity to embark on the path of cultivating immortals. Although there are four Zhuji Dan now, Cui Ning never thought that he could break through the bottleneck of foundation building at one time.

And judging from the cultivation that can continue to grow and the impurities on the body, this Zhuji Dan really has its magic, and it seems that it needs to take a few more pills to improve the physique to the point where it can build a foundation.

If it is someone else, there is only one Tsukidan, and the breakthrough fails. Either you can only choose to give up and die of old age in the end, or you can only desperately earn spirit stones and finally work hard for decades in exchange for another Tsukidan, but at that time, the medicinal effect of the first Tsukidan has long since dissipated.

Therefore, this is the reason why it is difficult to build a foundation for scattered cultivation, and those genius children with family background or sect background do not need to worry about Zhuji Dan at all, in addition to their qualifications, cultivation resources can also pile up a foundation building monk.

But Cui Ning is different, although he is not an inner disciple, and he does not have an elder as a backer, but he still has three Zhuji Dan in his hand, and there are also Tianluo Fruits that are effective for breaking through the foundation building.

What he is more concerned about is how many more pills are needed to complete the physical improvement and break through the bottleneck of foundation building!

After a few days of meditation, Cui Ning continued to take the second pill of Tsukidan.

The same taste of "Ice and Fire", the same mud appeared after absorbing the medicinal power, but the second time was far more slight than the first, and the impurities were much less than the first.

Next was to take the third pill, and when he took the third pill, Cui Ning found that the spiritual power in his body was undergoing strange changes.

The original atomized aura mass in the dantian has slowly converged and become viscous at this time, and there is a tendency to transform from gaseous to liquid.

And when the first drop of liquid aura appeared, a huge suction force appeared from the dantian, frantically inhaling the mist-like aura that poured in from the limbs of the body into the dantian.

And the aura in the body becomes less and less as it is continuously absorbed.

"Oops, the aura is insufficient!"

Cui Ning's face changed, but he didn't panic, but took out a red crystal clear fruit from the brocade box, just that day.

He swallowed the Tianluo fruit directly, and didn't even chew it to taste the taste of this heaven and earth spiritual thing.

After the Tianluo Fruit entered Cui Ning's body, it began to exert its effect, and the large amount of heaven and earth energy contained in the flesh of the fruit instantly made up for the spiritual energy in his body that was already about to be depleted.

Not only that, but the excess energy also began to converge towards the dantian like an aura.

I saw that as soon as this energy arrived at the dantian, the speed of the liquefaction of the spiritual qi mass increased greatly, although the progress of liquefaction was accelerated, but at the same time, the speed of absorbing spiritual energy was also increased.

Cui Ning didn't dare to be sloppy, and swallowed the second Tianluo Fruit, but what Cui Ning didn't know was that each person could only take one Tianluo Fruit, and the second one was useless.

At this time, Cui Ning made a difficulty, but soon thought of the Great Zhou Tian Cycle of the Sun Technique, which could quickly absorb the aura of the outside world. And this Qiankun Cave Mansion has already been filled with energy that can be cultivated for six months.

But Cui Ning didn't know if the sun trick could be cultivated, but he quickly laughed, this sun trick was taken from the Donghuang Bell, how could he not be cultivated, the Donghuang Bell is the magic weapon of the most yang and the right.

Sure enough, this trick did not disappoint Cui Ning, and the aura from the outside world poured into Cui Ning's body like a tide under the Great Zhou Tian Cycle, and was sucked into the dantian, and finally became part of that liquid state.

In this way, Cui Ning frantically ran the sun trick to absorb the aura in the cave, and time passed day by day, but he was unconscious.

＊＊＊＊＊＊

Time flies like a white horse, and it is more than three months in the blink of an eye.

On this day, a wave of spiritual power in the Qiankun Cave Mansion suddenly surged out of Cui Ning's body that was far superior to the previous one. I saw him open his eyes, and the look of surprise was indescribable.

The foundation has been built!

At the moment when Cui Ning successfully built the foundation, a bell suddenly rang on the glazed sea, as if it was celebrating Cui Ning!

And on the glazed sea, only immortal cultivators or demon beasts above the primordial infant can hear this bell, and then the entire glazed sea begins to surge.

And Cui Ning, the initiator of everything, didn't know that he was excitedly feeling the changes in his body at this moment.

Cui Ning looked back on the difficulties encountered by ordinary people with poor qualifications in cultivating from stepping into the immortal path to now succeeding in building a foundation, which was unimaginable to outsiders.

If they were to become the inner disciples of the three sects of the East China Sea, it was estimated that one Zhuji Dan would allow them to build a foundation easily. Look at yourself again, but there are three foundation building pills plus heaven and earth spirit objects, and in the end, there is this set of sun tricks to barely succeed in building a foundation.

The past is unbearable, and Cui Ning no longer thinks about the difficulties he has experienced. He casually cast a spell, feeling his abundant aura, and now he is already an immortal cultivator in the foundation building period.

With the experience of this breakthrough, Cui Ning knew that hard work alone was not enough, and the cultivation of immortals in the world required a large number of intensive cultivation pills in addition to fighting methods.

However, in the world of cultivating immortals, the elixirs, especially those of high-level cultivators, were basically refined by some alchemy masters.

And those alchemists are basically controlled by the sect and powerful families, and if outsiders want to buy pills, in addition to buying them, they need to provide their own medicinal materials and remuneration to ask alchemists to refine them on their behalf.

Cui Ning was also one of the first to cultivate immortals, one of the hundred arts of alchemy, and had a strong desire. He didn't dare to think about it before, but now that he has this Qiankun space, even if his qualifications are dull, he spends five times as much time on alchemy, isn't it okay?

Although Cui Ning has now built a foundation, what he wants in his heart is definitely not just to build a foundation, after all, his goal has always been to step on the path of immortality and attain immortality!
